嗨，我正在用 c 语言制作一个拼写检查器，它在字符串数组中有一个字典，并使用二进制搜索在字典中查找单词。
我的问题是我正在尝试从文件中读取文本并将文本输出回新文件，其中错误的单词突出显示如下：** 拼写错误 ** 但该文件将包含诸如 .,!? 它应该输出到新文件，但在将单词与字典进行比较时显然不存在。
所以我想要这个：
text file: "worng!"
new file: "** worng **!"
我一直在尽我所能解决这个问题，并且在谷歌上花了很长时间，但离解决方案还差得远。到目前为止，我已经编写了以下代码来读取每个字符并填充两个 char 数组一个小写临时用于字典比较，一个输入用于原始单词，如果没有标点符号则可以使用，但显然当标点符号存在时我会以这种方式释放空间我'确定有更好的方法可以做到这一点，但我找不到它，所以任何指针都会受到赞赏。
